A sand screening device for construction engineering comprises: stand (1), support balladeur train (2) and crossbeam (3), the stand is connected with the support balladeur train is perpendicular, and the top of supporting the balladeur train is provided with screening sand net mount (4), and the cross-section of screening sand net mount is L type structure, and screening sand net mount in put into screening sand net (5), a set of pulley (6) are installed to the below of screening sand net mount, a set of pulley mounting is connected with gag lever post (7) in the top of supporting the balladeur train, on the support body at the both ends of screening sand net mount, the gag lever post is L type structure. The utility model discloses be applied to the construction field.

Description

Sand screening device for constructional engineering

Technical Field

The utility model relates to a building engineering screening sand device.

Background

The building engineering is a general name of scientific technology for building various land engineering facilities. It refers to both the materials, equipment used and the technical activities carried out such as surveying, designing, construction, maintenance, repair, etc., as well as the objects of engineering construction. In the field of building engineering, yellow sand is one of materials commonly used in building engineering construction, in order to meet the use requirement of the yellow sand, a lot of purchased yellow sand needs to be screened in a later period, and most of construction sites still adopt a manual sand screening mode at present, so that the labor intensity of workers is high, the sand screening efficiency is low, and the sand screening effect is poor. When large-scale equipment is adopted for screening, the equipment cost is high, and the transportation and the moving are inconvenient.

Disclosure of Invention

The utility model aims at providing a building engineering screening sand device.

The above purpose is realized by the following technical scheme:

a sand screening device for construction engineering comprises: stand, support balladeur train and crossbeam, the stand with support balladeur train connect perpendicularly, the top of support balladeur train be provided with screening sand net mount, the cross-section of screening sand net mount be L type structure, and screening sand net mount in put into the screening sand net, the below of screening sand net mount install a set of pulley, a set of pulley mounting in the top of support balladeur train, the support body at the both ends of screening sand net mount on be connected with the gag lever post, the gag lever post be L type structure, just the horizontal face setting of gag lever post in the below of support balladeur train.

In the sand screening device for the building engineering, a frame body is connected to the middle position of the right side of a sand screening net fixing frame, the frame body is fixedly connected with the outer ring surface of a rolling bearing, the inner ring surface of the rolling bearing is connected with a rocker, the rocker is rotatably connected with a turntable, and the turntable is connected with a rotating motor.

The sand screening device for the building engineering is characterized in that a frame of a rotating motor is fixedly connected with a base plate, the base plate is installed above two supporting sliding frames, the supporting sliding frames and the stand columns are connected with reinforcing inclined ribs, and a cross beam is perpendicularly connected between the two stand columns on the rear side.

The utility model has the advantages that:

1. the utility model discloses when screening sand, at first place the screening sand net in the screening sand net mount, because the cross-section of screening sand net mount is L type structure, consequently can hold up the screening sand net, then start and rotate the motor, the output shaft that rotates the motor can drive the carousel and rotate, be connected with the one end of rocker in the quotation of carousel, the other end of rocker passes through antifriction bearing and is connected with screening sand net mount, consequently can drive horizontal migration about screening sand net mount through the rocker when rotating the motor, can screen the yellow sand on the screening sand net when screening sand net mount horizontal migration, reduce workman's physical power, improve the efficiency of screening sand.

The utility model discloses at the gag lever post of the side fixedly connected with L type structure of screening sand net mount, the horizon bar face setting of gag lever post is in the below of supporting the balladeur train, when screening sand net mount left and right sides vibration on supporting the balladeur train, can prevent that screening sand net mount is skew, makes screening sand king mount remove about on supporting the balladeur train all the time.

The utility model has the characteristics of simple structure, convenient operation etc, can be fast convenient filter the yellow sand, improved work efficiency.
